Sunlight Photosynthesis: 6CO 2 + H 2 6 H 12 O 6 + 6O 2 In the above reaction, sunlight supplies the energy to convert carbon dioxide and water to glucose and oxygen.Hydrothermal vents, which are hot springs on the sea floor, support exotic chemical-based ecosys-tems.
Submarine hydrothermal vents are geochemically reactive habitats that harbour rich microbial communities. There are striking parallels between the chemistry of the H 2 âCO 2 redox couple that is present in hydrothermal systems and the core energy metabolic reactions of some modern prokaryotic autotrophs.
